Overview
Epidemiology and Demographics
Sickle cell disease is known to have a high prevalence in Africa (specifically the sub-Saharan region), India, and the Middle East. Difference regions of the world display different frequencies of genotypes of the various sickle cell subtypes. Sickle cell disease is a condition that largely affects people of African descent. In a study of three cohorts in Nigeria and Sudan, the frequency of HbSS was 88-96%. The frequency of HbSC was 4-12%.[1] It affects 1 in 400 African Americans, and a total of 89,000 Americans.[2] In contrast, people from India have a lower frequency of the HbSS genotype (30-70%) and a higher frequency of sickle cell-beta-thalassemia (HbSB) genotype.[1] The heterozygote prevalence in India of sickle disease disease varies from 1-40%.[3]
There is a high frequency of emergency department visits by patients with sickle cell disease. Over a two-year period, there were a total of 97.579 visits amongst 8 states.[2] Amongst these visits, 52,107 warranted hospitalization.
